Rotted Wood Hardener rejuvenates damaged wood and makes it resistant to further deterioration. Used in conjunction with Epoxy Wood Rebuilder, expensive woodwork can be restored to its original appearance, often stronger than the original wood.

Rotted Wood Hardener features a unique, one-part formula which requires no mixing. It is water-based, environmentally friendly, and has no strong noxious odor. Its thin viscosity allows it to deeply penetrate into soft and rotted wood fibers before hardening and bonding with the wood to waterproof, regenerate and revitalize structural and decorative woodwork. Excellent for repairing windows, sills, wood boats, flower pots, etc.

 Use at temperature 45°F or above. Surface must be clean and dry. Remove loose, rotted, or flaky wood. Drill holes at downward angle for deepest penetration on vertical surfaces, or if soft fibers are more than 1/4" deep, or if treated area is under paint or finish. Pour or brush liberally onto wood. Let soak in and repeat until fully saturated. Rate of penetration depends on the wood porosity and deterioration. Allow to cure overnight. Wire away any excess from surrounding areas before liquid dries.


Wear gloves and eye protection. Avoid contact with eyes and skin. Wash thoroughly after handling. If swallowed, do not induce vomiting. Seek medical attention. Cured hardener is harmless and safe. Keep out of the reach of children.
